FAQ

CCTV cameras

What are cctv cameras?

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere.

Types of cctv camera?
  1. Dome CCTV Camera
  2. Bullet CCTV Camera
  3. C-Mount CCTV Camera
  4. Day/Night CCTV Camera
  5. Infrared/Night Vision CCTV Camera
  6. Network/IP CCTV Camera
  7. Wireless CCTV Camera
  8. High-Definition HD CCTV Camera.
How cctv camera works?

CCTV (Closed Circuit TV) uses one or more video cameras to transmit video and sometimes audio images to a monitor, set of monitors, or video recorder.

The difference between CCTV and standard TV is that standard TV openly broadcasts signals to the public. CCTV is not openly transmitted to the public.

CCTV uses either wireless or wired transmission to send the broadcast from the video cameras to the monitor(s) or recording device.

Most CCTV systems are used for surveillance, which can include security monitoring, spying, or safety monitoring.

How to install a cctv camera?

Below are the basic steps to install a cctv camera for your house or small offices. Please note this installation process in not for company or industry owners. We suggest companies or commercial area to go with a separate professional installation service.

A)Preparing your home or place

  • Make a diagram of your surveillance needs.
  • Buy the right package to suit your needs.
  • Alternatively, buy your cameras individually.
  • Set up a recording device and monitor.(DVR,NVR OR HVR)
  • Mount your camera to the wall.
  • Attach your camera to a power source.
  • Attach wired camera to your DVR.
  • Attach the monitor to the DVR.
  • Troubleshoot any connection issues.

B) Consolidating your Surveillance system

  • Create a central "surveillance hub." 
  • Use Siamese cables to wire your system effectively.
  • Use a power supply box to power multiple cameras through one outlet.
  • Attach each video cable to a separate DVR port.
  • Hide your wires.
What are analog cctv?Pros n cons?

Analog cctv system simply record  the moment activity for future access. However, since it does not broadcast actual live information, it is not practical for monitoring stores from a remote location.The picture quality is also low and often unusable, and it relied on human reliability as well, such as changing the tapes regularly.

Analog technology at one time served a purpose for security monitoring, but now digital CCTV is revolutionizing security measures and technology has evolved to allow for a more diverse security monitoring system. But if you have a low budget than you can go for analog cameras

Pros n cons:

The most common kind of CCTV out there mainly due to it being the oldest in the market place. Some consider this an ageing technology, beaten in image quality by other platforms such as IP. While some of this is true, analogue does have some positives going for it which are enough to sway the potential buyer.

Firstly, analogue CCTV has the widest cross compatibility of all the other platforms, making a replacement camera more “fit and forget” than other technologies.

Another major benefit to analogue is storage. Analogue CCTV kits use far less storage than the other platforms making it possible to record more footage to a hard disk than the other technologies.Less Storage equates to less cost which leads us to our biggest benefit of analogue. It's much cheaper than some of the other platforms.

Cost of analogue CCTV or its lack of, is perhaps its biggest selling point. Coupled with its strong cross compatibility, it's easy to see why it still remains a popular choice for surveillance.

What are ip cctv cameras? Pros n cons?

An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet.

Pros n cons:
IP CCTV has seen a huge rise in sales over the last few years with recent figures suggesting that IP CCTV makes up 50% of all CCTV sales globally.

IP systems have the benefit of superior image quality as there are no unnecessary conversions of the digital signal on its journey. It is not uncommon to see IP cameras with very high Megapixel sensors of 6MP or more.

This high Megapixel count equates to very high resolution images, resulting in very sharp picture quality.

Cross brand compatibility is not a strong point with IP CCTV and can cause some issues, while following the same protocol, specific features like motion detection sometimes to do not function correctly.

Being the more expensive of the surveillance options, its price is often the deal breaker for some people looking for an inexpensive way to keep an eye on things.

What are hd cameras? Pros n cons?

HD-SDI CCTV cameras, also known as HD security cameras, are capable of capturing video surveillance footage at 1080p resolution (1920 x 1080 pixels). These high definition surveillance cameras must be used with an HD-SDI surveillance DVR.

Pros n cons
HDSDI was the first to hit the market, but as with most first generation products it wasn't without its issues. HDSDI suffers from interference from strong RF. So installing them near WIFI Routers isn't really recommended. Mobile phone signals have been known to cause issues too.

HDCVI, much the same, has improved on the issues that HDSDI is prone to. It utilizes low frequency modulation and in doing so manages to avoid RF interference. It also improves on transmission range making it cable of up to 500 metres through coaxial cable. However, it was invented by Dahua and its future compatibility does not appear to be great, this is where HDTVI steps in…

HDTVI technology is the latest addition to the HD over coax family and has all the benefits of HDCVI. The biggest advantage of HDTVI is that it is an “open” chipset not being sold to any “single” manufacturer.

This is great for the consumer that likes to mix and match, searching for the best deals. Hikvision, the world's largest manufacturer of CCTV has adopted this technology for their HD over analogue solution.

We expect HDTVI to dominate this market space in the future due to its excellent cross brand compatibility.

Biometric Systems

What are Time and Attendance Systems?

Time and Attendance systems are automated systems which are used in managing and maintaining employee time and attendance records.

How are time and attendance of employees captured?

Employee time and attendance are captured with the following technologies,

  1. Fingeprint
  2. RFID
  3. Face Recognition
  4. Vein Detection

Some times probabilities of the above is used for special cases and physically challenged people/employees.

Are recorded data stored in the device or in the centralized data?

Attendance records are stored in the internal memory of the device which in turn can be sent to central server using the following process:

  1. push data technology
  2. Pull records via softwar
What is a push data technology?

The data stored in the device/s are pushed directly to the centralized server periodically or parallely as the punch records are fed/collected.

Why push data technology?

Push Data Technology is one of kind advance data retrieval and fetching technology. It allows the enterprises to simplify their complex way of maintaining employee records by providing a standalone global standard solution.

What benefits/cost savings will biometrics provide?

The usefulness of biometrics varies from application to application.To determine its true benefit, one must first develop and understand the operational requirements of application.

Biometrics can provide an automated means for identification of an individual on verification of a claimed identity.Before making a decision,one must ensure this task will meet the determined operational needs.

Biometrics can potetially provide cost savings through relocating security resources or diminishing the expenses associated with password maintenance,or it could cause extra costs by highlighting problems that were previously missed. The cost benefits vary from application to application as well.

Do biometric matches provide a 100%guarantee?

No technology can provide a 100%guarantee. The key is to determine where the system will be successful and how to implement it correctly for the application.

For example, a metal detector must have correct placement and sensitivity adjustments to work effectively and approprately  the same is true for a biometric system.

Access control

What are access control?

In the fields of physical security and information security, access control is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.

Types of access control?
  1. Elevator Controller
  2. Single Door Access
  3. Turnstiles
  4. Multi-door access control


What are the basic components of an access control system?

At its most basic, an access control system is composed of credentials, readers and a program interface.
A credential is the item used by an individual to gain access through a specific entry point.

Traditional credentials can come in the form of key cards, photo badges, key fobs, and cell phone tags. More advanced credential systems use your face, voice or fingerprints as your ID.


A reader runs credentials. Often a box next to your door, used in place of a traditional lock to read a credential (which serves as the key). Readers are programmed to grant or deny access to each individual based on their specific credentials.


The component of the system you interact with to program your credentials and readers is called the interface.

What is the difference between access control and managed access control?

Managed access control allows the user to keep their focus on their work, not their doors and alarms.
Basic access control systems can be purchased and installed by a vendor, or self-installed, but are not supported by a service staff.

With managed access control, a company assists you in running everything access control related at your property.

 A managed access control provider walks you through each step of the process and continues to work with you throughout the life of your system.

In addition to the installation and maintenance of your system, managed access control provides programming assistance (activating and de-activating credentials, changing permission levels, hours, etc.) and monitors your doors and office space.

Managed services are backed by 24/7/365 live operator support and can be reached at any time.

When a situation arises, trained operators follow a specific set of instructions, allowing you to keep your focus on your work, not on your doors and alarms.

 

Whether K 20 or K 30 for single door access control system?

K 30 is best suited where you want to restrict access using the fingerprint, card or password from one side of door and push button on the other side of door.

 As it comes with 12 Volt adopter so EM Electromagnetic Lock supply can be given through the adopter of K 30 machine itself.

What are the accessories required for access control system.

Controller, Electromagnetic Lock, Brackets depending upon the type or door and space.

Where to use X990 for access control system?

X990 is best suited where you want to have biometric access control from both sides of the door. 
On one side X990 machine can be mounted and on the other side F 12 reader can be used. 

Apart from these X990 can be used to fulfill various other requirements like centralized data access.

What types of biometric does your access control system work with?

Symmetry works with fingerprint, vein, iris, hand geometry and facial recognition biometric systems as standard. Integration with other types of biometric is usually possible.

We recommend use of a card plus biometric system for both security and practicality purposes.
